GRAIN-BINDER.

EPEQIFIGATION forming part of Letters Patent No. 323,001, dated July 28, 1885.

Application filed May 23, 1884. (No model.) Patented in Canada May 17, 1884. No. 19,371. i

To aZZ whom it may concern:

Be it known that we, J AMES \VEDLAKE, of the city of Brantford, in the county of Brant, in the Province of Ontario,Canada, machinist,

and LYMAN MELVIN J ONES, of the city of Winnipeg, in the Province of Manitoba, Canada, manufacturer, have jointly invented certain new and useful Improvements in Grain-Binders, and we do hereby declare that the following is a full, clear, and exact description of the same.

The object of the invention is to devise sim ple mechanism for controlling the twine during the period that the grain is being packed,

I 5 compressed, and bound; and it consists, essentially, of a rod operated by the motion of the needle-shaft and arranged to take up the slack twine passing through the needle and to simultaneously operate a tension-plate for holding the twine during the period mentioned.

Figure 1 is a perspective view of our device as it appears before the needle is brought into action. Fig. 2 is a perspective view of the device as it appears when the needle is thrown Fig. 3 is a perspective of the portion of the tension-bracket, fixed to the frame of the machine. Fig. 4 is a perspective of the tension-arm, which is pivoted to the tension-bracket. Fig. 5 is a cross-section of 3 the tension-bracket and tension-arm through a: y, Fig. 1, showing the bolt and spring for operating the arm.

In the drawings, likeletters of reference indicate corresponding parts in each figure.

As our invention relates merely to peculiar take-up and tension mechanism for controlling the twine, it is not necessary to show any part of the binding-machine other than those parts immediately connected with the improved 0 mechanism in question.

In the drawings, A and B represent portions of the frame of the binding-machine to which our mechanism is attached.

O is the needle-shaft; D, the needle, and E 5 the twine, which passes from the twine-box to the needle in the usual way, except that it is passed through our take-up and tension mechanism, as illustrated.

F is a tension-bracket rigidly bolted to the portion of the frame marked A.

G is a tension arm pivoted at a to the tension-bracket F.

b is a ledge formed on the bracket F to support the end of the arm G, as indicated.

A projection, d, is formed on the end of the arm G, as shown.

0 is a hole through the bracket F, and f is a similar hole made through the extensionpiece g, formed on the bracket F.

h is a third hole made in the bracket H, which is bolted to the frame A at a point near where the needle D passes. The twine E is threaded through the holes e, f, and h, and I also through the loop 1', formed on the end of the rod 1.

J is a hook-bolt fastened to the bracket F, and after passing through a hole, j, in the arm G has a spiral spring, is, placed on it and jammed against the arm G by the nut m. As this boltJ is fastened to the bracket F, and is aloose fit in the holej, the action of the spring is will force the loose end of the arm G against the ledge 12. The lower end of the rod I is connected, as indicated, to the end of the arm K. This arm K is pivoted at n to the bracket L, which is bolted, as indicated, to the portion of the frame of the machine marked B. The other end of the arm K has an oblong hole, 0, formed in it, through which the crank-pin passes. This crank-pin p is placed, as indicated, on the hub of the needle D, or a similar crank-pin so formed, but independent of the needle so long as it is fastened to the needie-shaft O. -,The effect of this connection between the needle-shaft and arm K is that the motion of the needle-shaft imparts a rocking movement to the arm, and consequently a vertical movement to the rod I.

' When the needle is down, as shown in Fig. 1, the crank-pin 1) will be in such a position that the rod I may be forced up against the projection d, formed on the end of the tensionarm G, and thus leave the tension-arm G clear of the ledge b, and as the loop t on the end of the red I will be on a line with the holes 6, f, and h, the twine E may be drawn freely through the said holes.

WVhen the needle is thrown up, as shown in Fig. 2, the crank-pin p, which of course moves with the needle-shaft G, carries up the end of I09 the arm K, which is attached to it, which movement of the arm carries down the rod I clear of the projection d. The spring 10 immediately forces down the loose end of the arm G against the edge I), compressing the twine E against the ledge b with a pressure equal to the strength of the spring, thereby giving the necessary tension to the twine, which tension can be increased or decreased by adjusting the nut at so as to strengthen or decrease the power of the spring is. As the loop t leaves the arm G it necessarily carries with it the twine, as shown in Fig. 2, and as the tensionarm G and ledge b on the bracket F are holding the twine between the loop i and the twinebox the twine drawn down by the loop 11 is taken from the needle, thereby effecting the desired and necessary take-up. When the needle D resumes the position shown in Fig. 1, the loop '23 resumes its initial position, lifting the arm G clear of the ledge b, and thus permitting the twine once more to pass freely through.

\Vhat we claim as our invention is 1. In agrain-binding machine, a spring-tension device, in combination with a release]- acting independently of'the binding-cord, the needle-shaft provided with a crank-arm, and connecting mechanism whereby the releaser is operated to release thetension device and allow the cord to pass freely, substantially as described.

2. In agrain-l'iinding machine, aspring-tension device and a takeup for the cord c0nneeted with and operated by the needle'shaft, and constructed to strike and release the tension, and when the arm is operated to take up the binding-cord permitting the tension to close on the cord, substantially as described.

3. The tension-bracket F, secured to the frame of the machine and having a hole, 6, through which the twine is threaded, and a ledge, b, to support the twine, in combination with the pii oted tension-arm G, actuated by the spring 70, and arranged to hold the twine against the ledge b, substantially as and for the purpose specified.

4. The tension-bracket F, formed substantially as specified, and the pivoted arm G, having a projection, d, formed on it, and actuated by the spring k, in combination with the rod I. operated by the motion of the needle-shaft and arranged to actuate the tension-arm G, substantially as and for the purpose specified.

5. The tension-bracket F, secured to the frame of the machine, the holes e f, the bracket H, having the hole h, through which the cord is threaded, as specified, the pivoted arm G,

provided with a projection, d, and arranged to rest on the ledge b, and the rod I, having a looped end, z, through which the cord is threaded, in combination with the pivoted arm K, one end of which is connected to the rod I and its other end to the crank-pin p, which is attached to and works with the needle-shaft O, substantially as and for the purpose specified.

6. In a grailrbinding machine, an arm, K,

pivoted to the frame of the machine,and having an oblong hole, 0, formed in it, through which the crank-pin p passes, which crank-pin is attached to the needle-shaft 0, in combination with the rod I, supported by the pivoted arm K, and having a loop, i, through which the twine is threaded, the whole being arranged and operating substantially as and for the purpose specified.
